Definitions

  • the invention relates to a ski boot with a shell and a shaft or a cuff pivotably articulated on the shell, in which the shell and shaft or cuff are connected to one another in the heel region via a spring element and a tension member acting on the spring element is pivotably fixed to the shell , wherein the tension member consists of at least two parts which are displaceable in the longitudinal direction relative to one another and the parts of the tension member can be releasably locked to one another in at least one displacement position, a first part of the tension member being pivotally attached to the shell and a second part of the tension member to the shaft or the sleeve is.
  • a number of different devices have become known for damping the movement of a shaft or a cuff relative to the shell.
  • a device between the shaft and the shell has become known, in which two components are telescopically guided into one another, one of the two components connected with the shaft or shell being immersed frictionally into the other component.
  • different damping of the movement is achieved with such a design.
  • the majority of the devices that have become known do not exactly represent damping, but rather a resilient limitation of the swivel path.
  • German utility model G 85 14 965 a device with a tension member passing through a helical spring has become known, in which the spring is more or less tensioned when the shaft is pivoted relative to the shell.
  • Training of the type mentioned at the outset corresponds to a previously known ski boot on the market.
  • a combined, resilient and damping element was used between the shell and the shaft, which, based on a preselected rest position, was able to dampen movements in both directions.
  • Such training is relatively complex and expensive and is also related to relatively large dimensions due to the design.
  • the invention now aims to provide a device of the type mentioned, which can absorb large forces resiliently with small dimensions and low wear or low stress, in particular of the bearing points, and which at the same time makes it possible, with simple means, to pivot the spring free of spring forces To ensure the shaft in a walking position or upright position of the shaft from the original position.
  • the ski boot according to the invention should not be able to be built much more heavily and not substantially larger than normal ski boots without such devices by the suspension or damping of the movement of the shaft in front of it.
  • the ski boot according to the invention with a device of the type mentioned essentially consists in the fact that the spring arranged between the second part of the tension member and the shaft or the sleeve encompasses the outside of the second part and is displaceable in the axial direction of the second part and is arranged in the respective displacement position lockable spring plate and a bearing pin having washer, the bearing pin having washer on the outside of the second part in the axial direction of the same is displaceably guided against the force of the spring.
  • a spring plate bearing pin on the one hand a stable support of the spring forces and on the other hand an articulated connection of the part of the tension member encompassed by the spring on the shaft or on the sleeve is achieved.
  • the tension member is divided into several parts, locking and unlocking of these parts can also be accomplished in a simple manner, so that despite spring loading one of the components of the tension member is released by simple unlocking and the shaft can be pivoted unloaded into a walking position.
  • the operating position can be set, in which primarily the pivoting into the template takes place against the force of a spring, so that a certain amount of template damping is achieved.
  • the initial position is set, in which a minimum template or a maximum reserve can be specified, and the subdivision of the tension member into several parts enables appropriate stops for the maximum reserve, as well as an adjustment of the template angle with constructive to realize simple means. At the same time, a high degree of stability is ensured, and it can be found with small components.
  • the design is such that the first part of the tension member, which is pivotally attached to the shell, is arranged so as to be immersed in the second part of the tension member which penetrates a bearing point on the shaft or the sleeve. Characterized in that one part of the tension member is immersed in the other part of the tension member is guided, good guidance of the individual parts of the tension member is ensured or into one another, and the spring forces can be brought into effect in an exactly adjustable manner in the axial direction of the tension member.
  • the design is advantageously made such that the second part of the tension member penetrating the bearing point on the shaft or the cuff stops to limit the swivel path the cuff or the shaft in the reserve in the locked position of the two parts of the tension member.
  • Such a design allows the second part of the tension member, which cooperates directly with the spring, to be held on the cuff or on the shaft and, in a particularly simple manner, enables the first part, which is immersed in this part, and which is pivotably articulated on the shell to decouple from this second part to achieve a release in the walking position.
  • the formation of the further, spring plate movable along the tension member as part of the storage in the form of a bearing washer with journal also offers the possibility in a simple manner to exactly limit the minimum template or maximum reserve and the same component as a counter-stop for a stop on the To pull outside of the part of the tension member passing through the bearing washer.
  • the training is hiebei made so that the bearing pin has the maximum pivoting of the shaft or the sleeve in the reserve with the stops to limit the reserve on the outside of the second part of the tension member and that the bearing pins in recesses or openings one fixed to the shaft or the sleeve, in particular one piece with the shaft or sleeve, Bearing block are included.
  • a particularly simple way of unlocking parts of the tension member which are non-positively connected to one another in the pulling direction can be achieved in that a spring-loaded bolt is provided for locking the two parts of the tension member which are releasably connected to one another and which is in aligned, radial bores of the parts of the tension member can be locked.
  • a spring-loaded pin can be brought out of engagement with corresponding aligned bores or recesses against the force of a spring, so that at least one of the components of the tension member is freely displaceable relative to the other components of the tension member.
  • the original basic setting for the minimum template or the basic setting of the spring force is not changed in any way with such a release or unlocking.
  • the design is advantageously made such that the Shell pivotally articulated part of the tension member is encompassed by a coupling member, with which the part pivotably hinged to the shell is releasably lockable, and that the coupling member is non-positively and length-adjustable connected to the spring-loaded part of the tension member.
  • Such an additional component or such a coupling member allows small and stable devices for adjusting the basic setting of the original position to be accommodated, the design advantageously being such that the coupling member partially encompasses a knurled nut which on the outside of the spring-loaded part of the tension member is screwable.
  • a knurled nut can be screwed through the coupling member at exposed locations, so that the basic setting and thus the template can be preset by the variable length fixing of the coupling member on the part of the tension member interacting with the spring.
  • FIG. 1 shows a ski boot according to the invention with a multi-part tension member connecting the shell and the shaft or the cuff; 2 shows a section through the tension member according to the invention along the line II-II of Figure 1 in an enlarged view.
  • 3 shows a section along the line III-III of FIG. 2 through the locking mechanism, and
  • FIG. 4 shows a section along the line IV-IV of FIG. 3.
  • Fig. 1 denotes a ski boot, in which a shaft or a cuff 3 is articulated on a shell 2 so as to be pivotable about an axis 4.
  • locking members 5 are indicated on the shaft.
  • a tension member 6 is provided, which consists of a first part 8, which is fixed on the shell 2 pivotably about an axis 7, and a second part 10, which is pivotable about an axis 9 on the shaft or the sleeve 3, and a coupling member encompassing the part 8 11 is composed, as will be explained in more detail below with reference to the following figures.
  • a schematically indicated spring 12 interacts with the part 10, the damping hardness of which can be adjusted by means of a knurled nut 13.
  • an unlocking member 14 is indicated on the coupling member 11 in FIG. 1.
  • the first part 8 of the tension member which can be fixed on the shell 2, is fixed on the lower shell pivotably about the axis 7 and is overlapped by the coupling part 11.
  • the part 8 is immersed in the second part of the tension member 6, which can be pivoted on the shaft or the sleeve 3 about the axis 9, this second part being encompassed by the spring 12, the damping hardness of which can be adjusted by the knurled nut 13.
  • the pivot axis 9 of the second part 10 is defined by bearing journals 15, which are supported by a disk 16 serving as a spring plate for the spring 12, and which are pivotably mounted in a bearing block on the shaft or the sleeve 3 in a manner not shown.
  • a second spring plate 17 for the spring 12 is carried by the knurled nut 13.
  • the tension member In order to limit the maximum reserve in the locked state of the parts 8 and 10 of the tension member which are displaceable in the longitudinal direction with respect to one another, the tension member also has stops 18 which cooperate with the disk 16 and which limit a rearward movement of the shaft or the sleeve 3.
  • the distance of the stops 18 from the articulation axis 7 of the pivotable, first part of the tension member 8, which is articulated on the shell 2, can be adjusted via a Coupling member 11 mounted knurled nut 19 are adjusted, which cooperates with a thread 20 provided on the outside of part 10.
  • the lock is again schematically designated 14 in FIG. 2.
  • the locking of the two parts 8 and 10 of the tension member 6 which are displaceable in the longitudinal direction with respect to one another is shown in detail in FIG. 3, the same reference numerals having been retained for the same components.
  • the first part articulated to the shell 2 is again designated 8 and is encompassed by the part 10 interacting with the shaft.
  • the knurled nut 19 arranged in the coupling member 11, which also has the locking mechanism, is again provided for the adjustment of the template.
  • the locking is made possible by a bolt 22 loaded by a spring 21, which is guided in a bore 29 in the coupling member 11. In the locked position shown in Fig.
  • the head 23 of the bolt engages in a radial recess or bore 24 of the part 8 and results in a locking in the longitudinal direction of the mutually displaceable parts 8 and 10 via the coupling member 11, since the with the shaft cooperating part 10 is held immovably by the knurled nut 19 relative to the coupling member 11.
  • an actuating element 25 of the bolt 22 moves counter to the force of the spring 21 in the guide 26, the head 23 of the bolt disengages from the bore or recess 24 in part 8, so that this part 8 in Part 10 is displaceable in the longitudinal direction and thus the shaft or the cuff 3 can be pivoted into a substantially upright walking position relative to the shell 2 over a large angular range.
  • the part 8 In order to prevent the part 8 from escaping from the part 10 surrounding it, the part 8 has an enlarged head region 27 and the part 10 has stops 28 on its inner surface, as can be seen from FIG. 2.
  • the two parts 8 and 10 which are displaceable in the longitudinal direction to one another, in the once selected template position, it is sufficient to move the operating element 25 of the bolt 22 in the direction of the position shown in FIG. 3, whereupon taking a corresponding template of the shaft or the sleeve 3 relative to the shell and thus a corresponding displacement of the part 8 relative to the part 10 when the head 23 is aligned with the recess 24 in part 8 of the bolt in part 8 and thus a locking is achieved.
